MUD-HOOK.

specification of Letters Patent.

Application ledMarc-h 5, 1921. Serial No. 449,878.

a mud hook of simple, durable and inexpensive construction.

More particularly it is my object to provide a mud hook comprising spaced angle iron members having a .non skid block def tachably received between the spaced angle iron members. The angle iron members being curved from end to end so as to conform to the contour of the tread of the tire.

Still another object is to provide a' non skid member or mud hook, having a central non skid block detachably fixed to the mud hook; and hinged portions so that the parts may adjust themselves to the contour of various sizes of tires.

With these and other objects in view, my invention consists in the construction, arrangement and combination of' the various parts of my device, whereby the objects contemplated are attained, as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which:

Figure 1 is a central, sectional view taken through a tire showingmy device installed thereon.

Fig. 2 is a top, plan view of my device,

My device comprises'a 'pair of spaced angle iron members 13 and 14 which are, similar in construction and having their,y ends slightly bent as at 15 so as to conformV to the contour vof the tire 12. In order to properly hold the angle iro members 13 and 14 spaced from each other and against movement relative to'each other, I provide spacing rods 16 and 17 which have their ends screw threaded as at 18. The rods 16 and 17 are extended through registering openings provided in the Vportion 15 of the angle iron members 13 and 14.

Nuts 19 and 20 are fixed to each of the" screw threaded ends 18 ofthe rods 16 and 17. The nuts 20 rest against the inner side of the angle irons 13 and 14; while the nuts 19 rest against the outer sides, as illustrated in f Fig. 2 of the drawings. l

F rom the construction of the parts just described it will be seen that I havel provided a rigid mud hook member whichis comparatively simple and yet very strong. l

vThe endsof the portions 15 of the angle iron members13 and'14 are bent upon themselves so as to form lloops or. hook pori tions 21. i f

Received. in the loops 21 are the chains'22, which have their free ends connected together by a link 23. The ends of the chains 22 are inclined toward each other so that the` links 23.

Extended through the links 23 is a strap 24 having a buckle' device v25 fixed to one of; its ends. The free endof'the 'strap 24 isv designed to coact with the tongue 26 of the. buckle device. v

The chains 22 and the strap 24 extend around the tire for holding the mud hook in positionf The strap 24 passes around the rim 11 and the felly 10;

Received between the angle irons 13 rand 14, and between the spacing rods 16 and 17 is a non skid member 27 whichis angular inv` l i outline.- The non skid member 27 is provided with openings which register with" openings inthe angle iron lmembers 13 and 14. y l Extended through the openingsfare the bolts 28 which provide a means for fastening the non skid member 27 to the angle irons 13` and 14. l i

It will be lseen that the-non skid block or A l member 27 may be removed from the mud hook easily.

It will 'be seen that the angle iron members 13 and 14 provide gripping surface for providing traction Jfor the wheel while the spacing. rods 16 and 17 and-'thesides of the non skid block 27 prevent sideward skidding 105 of the wheel. i n

The non skid block 27 which has its upper.

edge flush with the upper edge or the angle iron members 27 adds rigidity to the entire Y mud hook so that a comparatively light 110 Patented Dec. 13,1921. I

free ends may be connected together by the' 75 angle iron may be used in my improved construction.

By making the non skid block 2,7 I am able to remove it when it comes worn from use and easily install a new one.

The portion 29 is provided with spacingrods 16 andnl similar to the form of device shown in Fig. 2. The hinged portions 29" are provided` with loops 21 in which are received the ends of the chains 22.

By providing. the hinged portion 29 it will be seen that the mud hook will readily and easily conform to the various contours of various sizes of tires. y

The parts of the mud hook as shown in Fig. 3 will maintain sufficient rigidity so as to successfully use this form of device as a mud hook.

The advantage of this form is the adaptability of it to various sizes of tires.

It will be seen that my device is made of simple parts,some of the parts being. interchangeable. for repairs, which makes the f device very practical.

Somechanges may be made in the construction and arrangement of the parts of my device without departing from the real spirit and purposeof my invention,- andit is my'intention tocover by my claims, any

modified forms of structure, or use of mechanical equivalents, which may be reasonably includedwithin their scope.

I claim as my invention:

1. Al mud 'hook comprising a pair of spaced angle-iron members adapted? to extend transversely across the tread of aI tire, a pair of spacing rods extended through y registering, openings in said angle iron mem.-

bers for spacing said angle irons relative to each other, a non skidv block received be:-

tween said angle iron membersand between sa-idspacing. rods, said non skid blockbeing detachably' vfixed to said angle irons, the upper edge of said non skid block being flush with the upper edge of said angle iron mem-y bersploops formed on the'ends ,of said' an' .le iron members, chains fixed to each of te endsin said loops, the free ends .of Ythe adjacent chains being fastenedtogether, and a strap and buckle device fixed to saidk chains for securingsaid mud hook toa wheel as `and for the purposes stated.

2. A mud hook comprising a pair 'of l spacedangle iron members adapted to extend transversely across the tread of a tire,y

a pair of spacing rods extended through registering openings in said angle iron members for spacing said angle irons relative to each other, a non skid block received between said` angle iron members and between said spacing rods, said non skid block being detachably fixed to said angle irons, the upper edge of said'non skid block'being flush with the upper edge of said angle iron members, loops formed on the ends of said angle iron members, chains fixedto each of said ends in saidloops, a pair of links for fastening the free endsfof thel adjacent chains together, and a s trap and: buckle device fixed to said links, whereby theentire mud hook may be secured to a wheelV for the purposesy stated.
